CLOCK.

SPECIFICATION forming part of Letters Patent No. 298,557, dated May 13, 1884.

Application filed June 7, 1883. (No model.)

1'0 aZZ whom it may concern:

Be it known that I, SAINTEME DIOLOT, of the city, county, and State of New York, have invented a new and Improved Clock, of which the following is a full, clear, and exact description. a.

The object of my invention is to provide a new and improved clock in which visible hands are dispensed with, and movable ures are used in place of the same.

The invention consists in a clock or other time-piece having magnets on the ends of hands, which are arranged behind the dial, on which butterflies or other figures of magnetic material are placed, so that they can be carried over the dial by the action of themagnets, whereby the said figures indicate the time by their positions on the dial.

The invention also consists in various parts and details and combination of the same, as will be fully set forth hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a face view of my improved clock with the dial-plate removed. Fig. 2 is a cross-sectional elevation of the same with the dial-plate applied.

The hands A B consist of U-shaped bars mounted centrally on the shaft 0, in a manner that will be described hereinafter. Horseshoe-magnets D and E are held on the ends of the bars A and B, respectively, and on the opposite ends of the bars balancing-pieces F and G are held. Thereby the magnets will be counterbalanced, and the hands orbars A B can be turned very easily. The ends of the shanks of the magnets D E are close to the inner surface of the dial-plate H, which is made of paper, parchment, calf-skin,very thin iron, magnetic metal, 860. The larger or minute hand, 13, is below the smaller or hour hand, .A, and is bent downward at the ends to form Ushaped recesses to permit the magnet and balancing-piece of the hour-hand to pass when the hands or bars revolve, as the hand 13 revolves twelve times for every revolution of the hand or bar A. The bar or hand B is fastened to a collar held by friction on the shaft 0, so that the hand or bar will turn with l the shaft. The hand A is secured to a collar, J, loosely mounted on the shaft 0, and made integral with a cog-wheel, K, engaging with a pinion, L, made integralwith a cog-wheel, M, engaging with a pinion, N, rigidly mounted on the end of the shaft '0. The combined pinion L and cogwheel M is pivoted on one end of a plate, 0, pivoted on the end of the shaft Cand prevented from turning by a pin, P, projecting downward from the under side of the dial-plate into a notch or slot in the plate 0. The hands or bars A B are turned on the shaft 0 in the same manner as the usual hands of a clock. Two small ornamental sliding de vices, R S, or figures made wholly or partly of magnetic metal, are placed on the outer surface of the dial, the ends of the magnet being on the inner surface of the dial. As the magnets travel around the dial, they draw the butterflies or figures R S along, and the positions of these figures on the dial-plate show the time. The dial may be provided with the usual numbers, or with flowers, emblems, 850.

The clock appears to have no hands, as the hands are not visible, and the means for moving the figures R S over the dialplate are not visible.

The works can be of the usual construction, with the exception of the parts above mentioned.

I am aware that in an electric indicator for steamboilers a loose pointer or index has been arranged in case provided with a graduated surface, so as to be moved up and down over the said graduated surface by the magnet connected to a float in the boiler, to indicate the position of the water-line in the said boiler, and Itherefore do not claim such invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A clock or time-piece containing the following elements, operated in combination,

namely: an ordinary dial and clock mechanism, hour and minute hands worked by said mechanism, arranged behind the dial, provided with magnets that are adapted to attract and hold suitable devices in position in contact with the face of the dial, and cause said devices to slide on the face of the dial to indicate the time, all substantially as herein shown and described.

Ina clock or time-piece, the combination, with the dial, 01 devices that slide upon the front face thereof, and of magnets that are revol ved behind the dial by the clock mechanism, substantially as herein shown and described, whereby the time will be indicated upon the time of the dial by the shil'tingot' the sliding devices, as set forth.

3. In a clock or time-piece, the sliding devices It C, adapted to slide on the face of the dial and to be moved thereon, so as to indicate the time by means of magnets operated by clock-work behind the dial, substantially as shown and described.

In a clock or tii'ne-pieee, the combination, with the clock mechanism and the back of the dial, oi' the U-shaped-hamls or bars arranged one within the other, each bar or hand carrying a magnet and operated as described, whereby two independent sets of devices are made to slide and travel upon the face of the dial in concentric circles of different diamel ter, to indicate the hours and minutes, as set forth. I

5. In a clock, the combination, with the works and the dial, of the shaft 0, the hands A 13, having the ends bent', and of the magnets D E, and the balancingpieees F G on the ends of thehan ds,substantially as herein shown and described,

6. In a clock, the combination, with the works and dial-plate, of the shaft C, the hands A B, carrying magnets and balancing-pieces on the ends, the collar (1', provided with a eog-wheel, 1(, the pinion L, the cog-wheel M, and the pinion N, the plate 0, and the pin 1. on the under side of the dial, substantially as herein shown and described, and for the purpose set forth.
